Starting in Firefox 43, we have decided to make Java run in a separate process just as all other plugins do. This was done for several reasons:
* for security reasons: the in-process rendering codepath was subject to some unfortunate re-entry conditions that were potential security holes * for code maintenance: with this change we didn't need to support in-process plugins in Firefox at all, and that greatly reduces the complexity in the plugin code * to prepare for e10s: with e10s plugins must run in a separate process There is a bug in some versions of the Oracle Java plugin that when it displays a modal dialog box, it doesn't spin the event loop properly. This means that certain dialog boxes, such as certificate warnings and plugin activation notifications, cause Firefox to stop painting. With the move to the separate process, we now show a warning when the plugin is stuck like this and after 45 seconds we will the unresponsive plugin. So if you are in a situation where you see those modal dialogs, you probably do need to update the Java plugin to fix this problem. --BDS On Tue, Apr 19, 2016 at 11:24 AM, Urbanski Tomasz <[email protected]> wrote: > > Thank you for your reply. > > > > I am testing the 32bit version of Firefox 45ESR.
